CORNER BEAD Filed March 1, 1929 Patented July 1, 1930 UNITED STATESPATENT OFFFI'CB JOHN 3. WINTER, OI WARREN, OHIO, ASSIGNOR, BY MESNEASSIGNMENTS, 'I'O UNITED STATES GYPSUM COMPANY, OF CHICAGO, ILLINOIS, ACORPORATION OF ILLINOIS CORNER IBEAD Application filed March 1, 1929.Serial 1%. 848,985.

This invention relates to improvements in corner beads and, moreespecially, to a metal corner bead that may be easily and cheaplymanufactured, and which is strong 5 and durable.

In the manufacture of corner beads heretofore, it always has been aproblem to make the product properly and, at the same time, to getenough material in the head to make the same rigid and stiff, leavingthe wings sufliciently flexible to permit the attachment of the cornerbead. This problem has been solved by my invention, which incorporates alight piece of expanded metal for the wings,

said metal being bent on a longitudinal median line to form a projectingfolded edge. Inside of this edge, there is laid a wire and a strip ofsheet metal is crimped over the folded edge holding the wire therein.This makes a very stiff bead because it permits the use of a narrowstrip of heavy material which,

when reinforced by the wire, gives an ex- .ceedingly stifi' product, andalso looks the mesh in" the head of the bead. Another feature of myinvention is the ability to use non-rusting metals, such as zinc orcopper, for the nose or bead, and still use steel for the wings. Inwarm, moist climates, it is advisable to use 'a non-rusting metal at theexact corner, although such metal is ordinarily too expensive to permitits use in the construction of the entire device.

. Other features anTadvaTntages of my invention will appear more fullyas I proceed with my specification.

In that form of device embodying the features of my invention shown inthe accompanying drawings, Figure 1 is a view in perspective; and Fig. 2is a view taken as indicated by the line 2 of Fig. 1.

As shown in the drawings, the corner bead includes a strip of expandedmetal, as indicated by 10, bent on a longitudinal median line,'asindicated by 10, to form two wing portions 10", 10" adapted to be nailedto the studding or wall 11 in any convenient manner, as, for example, bymeans of the staples 12.

The expanded metal, being bent at 10,

forms there a projecting folded edge, and inside of this folded edgethere is placed a wire 13, said wire being held therein by means of'astrip of sheet metal 14 crimped over the folded edge 10. The sheet metal14: has a rounded outer edge l4: with two inwardly projecting,substantially parallel marginal portions 14:", 14*, the extreme inneredges thereof being flared outwardly slightly, as indicated by 14, 14.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims,

in which it is my intention to claim all novelty inheret in my inventionas broadly as possible, in view of the prior art.

' What I regard as new, and desire to secure by Letters Patent, is:

1. A corner bead including, a strip of expanded metal bent on alongitudinal line to form two wing portions substantially at rightangles to each other and a projecting folded edge, a wire lying insideof the folded edge, and a strip of sheet metal crimped over the foldededge and holding said wire therein.

2. A corner bead including, a strip of expanded metal bent on alongitudinal median line to form two wing portions substantially atright angles to each other and a projecting folded edge, a wire lyinginside of the folded edge, and a strip of sheet metal crimped over thefolded edge and holding said wire therein.

3. A corner bead as claimed in claim 1, in

which the sheet metal is provided with a rounded outer edge and with twoinwardly projecting, substantially parallel marginal portions.

4. A corner-bead as claimed in claim 1, in which the sheet metal isprovided with a rounded outer edge and with two inwardly projecting,substantially parallel marginal portions, the extreme inner edges ofsaid portions being flared outwardly.

In testimony whereof I have hereunto set my hand this 21st day ofFebruary, 1929. JOHN R. WINTER.
